OS Security and Endpoint Capabilities
Imagine an enterprise network as a sprawling, decentralized metropolis. Historically, security architects built massive perimeter walls—firewalls and gateways—expecting them to keep adversaries out.

Modern infrastructure, however, operates on a different reality. The perimeter has dissolved. Employees access sensitive data from coffee shops, branch offices, and home networks, meaning the modern battlefield is the endpoint itself and the communication protocols binding these disparate nodes together.

Securing this environment requires shifting our focus from the network perimeter to the operating systems, the endpoints, and the primary vector of business communication: email.
